Abstract

The data of the Coronas F satellite and other spacecraft were used to show that, in October-November 2003, global variations in brightness occurred in all spectral regions of the solar electromagnetic radiation. The variations were asymmetric in heliolongitude. This phenomenon was accompanied by an extremely strong energy release in the form of coronal-mass ejections and solar flares. The most powerful of them took place on the solar side that was characterized by an enhanced brightness even before these events. As a result, superimposed corotating and sporadic disturbances, which are partly correlated, can be traced in parameters of the solar atmospheric radiation, flows of the solar-wind plasma, and heliospheric magnetic field.
